The city flourished, and within 10 years had reached a population of approximately 550, but because of the drinking and carousing of the numerous railroaders it gained an unsavory reputation.

[5] On February 11, 1861, Abraham Lincoln stopped in State Line on his way from Springfield, Illinois, to Washington, D.C., for his inauguration.

He dined at the Frazier Eating House, then gave a short speech to a crowd in the public square before resuming his journey.

A historical marker on the site commemorates the event, and records the words which Lincoln spoke: Gentlemen of Indiana: I am happy to meet you on this occasion, and enter again the state of my early life, and almost of my maturity.

Again, gentlemen, I thank you for your warm-hearted reception.The town's post office was established in July 1857, with Robert Casement as the first postmaster, and continues to operate today from a newer building on Woodard Street.

Grain elevators were erected in the fall of 1857, but fires in September 1900, December 1932 and June 1984 each completely destroyed the structures, which were subsequently rebuilt.

State Line's grain elevators are currently operated by Archer Daniels Midland of Decatur, Illinois, and see considerable activity during harvest time.

The KTFD sponsored for a number of years an annual town festival called the State Line Fun Days, but this is no longer held.
